When I first heard this song Thank you, the second song from Mamo's latest single Kanon, I thought "wow the chorus sounds like Rebecca Black's Friday", but then upon second hearing I fell in love with this song because the lyrics are so beautiful. I'll try to translate the lyrics below. The kanji lyrics are adapted from here. You can listen to the song here.
THANK YOU by Miyano Mamoru (宮野真守) English translation
Although we're so close together,
There's things which I haven't told you about,
“I found my soul a best friend”
"Just tell me how to get straightforward".
“I found my soul a best friend”.
“I found my soul a best friend”.
When you place your hand on my chest,
Your face is the first thing that floats to my mind.
“Well just you and you and you”.
“Well just you and you and you”.
But it feels awkward,
Because there's still words I haven't spoken to you.
Again and again thank you.
I say these words to you, the one who found me,
Again and again thank you.
I say these words to you, the one who found me,
"I'm glad I met you".
If I can say these words through a song, thank you.
For being able to spend each day laughing with you, my dear,
If I can say these words through a song, thank you.
For being able to spend each day laughing with you, my dear,
I say thank you.
Thank you, thank you, lemme say I thank you.
Thank you, thank you, now and forever.
Thank you, thank you, lemme say I thank you.
Thank you, thank you, thanks*(1), I thank you.
This isn't just a mere (good) matter,
Thank you, thank you, lemme say I thank you.
Thank you, thank you, now and forever.
Thank you, thank you, lemme say I thank you.
Thank you, thank you, thanks*(1), I thank you.
This isn't just a mere (good) matter,
But an overwhelming feeling of love.
Because I have met you,
So I do not feel discouraged anymore.
“I found my soul a best friend”
In this manner I'll honestly convey these feelings to you.
“Well just you and you and you”
I'm still a little embarrassed,
But I'll give it my best (shot) today.
Thank you, thank you, lemme say I thank you.
Thank you, thank you, now and forever.
Thank you, thank you, lemme say I thank you.
Thank you, thank you, thanks, I thank you.
Again and again thank you.

Although seasons change,
I'll still keep on reaching out for you.
“Well just you and you and you”.
Because I want to see your smiling face,
I'll keep running to you again.
Thank you, thank you, lemme say I thank you.
Thank you, thank you, now and forever.
